My 22RE powered 85 4Runner & my 97 with a 3.4 both get the same milage 20MPG @ 70MPH 22MPG @ 55MPH. 3.4 has about twice the HP and allows me to pass on the Xway without using a calender to plan. 3.4's are pretty pricey but if you think you need the power go find a wrecked 3rd gen 4Runner and pull motor trans and all the wiring. One of the mags did a swap a few years back sourcing alot of the stuff from a shop in CO that specializes in them. They may have started with a 3.0 though. I have never not been able to go somewhere because of the 22RE though and they are a lot cheaper. I am not real familiar with which trans/T-case is which as I have not had to mess with any of them. Stay away from the 3.slo motors especially with an auto. The gas mileage sucks and they don't seem to have anymore power.

Ors is no more. Toyota only swaps is the place to look for 3.4 info. I wouldn't waste time or money on a 22re....go for the 3.4.

As one that owned a couple Toys with 22REs, they are excellent motors. I witnessed my buddy waterlog his '85 4Runner with a 22RE. He pulled the spark plugs and it fired up. I would run like crap for a while but would be back to it's gutless self in a few hours. And he did that twice that I know of.

I stand by my first post. I have had 3 22re's , 2 3.4's, and 2 3.0's. 3.4>22re>3.0. The 22re is ok for a bone stock truck that will never see more than 55 mph or a trailrig with super lpw gears and dual cases....anything other than that forget it.....i can't wait to ditch my current one.

Why the 55 mph limit on the 22RE? I had one that I drove 80-90 mph everyday down 696, my 85 will still top 90 on 33"s with 4.56 gears. It takes a while to get there. I've drowned it on t-day, thawed it out and changed the fluids to run it for Sno-Blind. Gotta get the synthetic lube out of the trans the syncros dont like it. Gonna put 35's on it for t-day this year.

w56 trans are strong A and B are top shift C is forward shift stay away from D and E
g52 is ok but w56 is stronger. theres a 4runner in northern mi for trade or sale with 3.4l 76,000 rolled auto trans

like they said 3.0 sucks go for the lexus v8 way more power than all these little motors. dont bother with the 3.4 if your going for power doe the lexus v8! or keep the adaptors and run a 302.
I love the 22r and 22re great reliable little rebuild work only one head gasket one timing chain only 4 to re ring go to v6 and your doing double . id stay with 4cylinder unless i was planning on racing or towing a house

22r little 22re little more 3.4 allot more lexus v8 still allot more 2rz-3rz still allot of work!
had a friend in oregon who had a 350 in his yoat, that blew, so he found a 22r and trans bolted together and threw them in he still driving this truck almost over a year, no clue on motors history either i have the drive lines also its best to do it that way

Figure out what you are going to do with the vehicle and what your budget is. More power is always nice but you end up paying for it one way or another, either fuel milage or broken parts. If you have the adapters for a 302 they are cheap & simple to work on. A properly set up 4Runner with a 22RE should get you anywhere you need to go reliably & economically. My V8 powered Broncos pretty much sit in the garage cause I can just throw the battery in my 4Runner, fill it up drive it to the Mounds, wheel all day then drive it home and still have fuel left.

My friend that tried making his 22RE water-powered ended up putting a 4.3 Chevy with a throttlebody in it. That was a pretty good fit and wasn't a big parts breaker. Exhaust manifolds off a Chevy Astro van were used. It seems to me he was able to use the Toyota ECU too but it was @ 15 years ago I helped him do it . There were only 5-7 wires you had to hook up IIRC.

I would agree with BOGDOG though. Figure out what you want to do with it. I personally would stay with a 22RE or maybe the Benzo swap I mentioned.
